Hairpin lace is a lace-making technique that uses a crochet hook and two parallel metal rods held at the top and the bottom by removable bars. Historically, a metal U-shaped eponymous hairpin was used. Hairpin lace is formed by wrapping yarn around the prongs of the hairpin lace loom to form loops, which are held together by a row of crochet ...
Hairpin technology is a winding technology for stators in electric motors and generators and is also used for traction applications in electric vehicles. In contrast to conventional winding technologies , the hairpin technology is based on solid, flat copper bars which are inserted into the stator stack.
The beta hairpin (sometimes also called beta-ribbon or beta-beta unit) is a simple protein structural motif involving two beta strands that look like a hairpin. The motif consists of two strands that are adjacent in primary structure , oriented in an antiparallel direction (the N-terminus of one sheet is adjacent to the C-terminus of the next ...
A hairpin or hair pin is a long device used to hold a person's hair in place. It may be used simply to secure long hair out of the way for convenience or as part of an elaborate hairstyle or coiffure. The earliest evidence for dressing the hair may be seen in carved "Venus figurines" such as the Venus of Brassempouy and the Venus of Willendorf.

A hairpin turn (also hairpin bend or hairpin corner) is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn about 180° to continue on the road. It is named for its resemblance to a bent metal hairpin. Such turns in ramps and trails may be called switchbacks in American English, by analogy with ...
The hairpin filter is another structure that uses parallel-coupled lines. In this case, each pair of parallel-coupled lines is connected to the next pair by a short link. The "U" shapes so formed give rise to the name hairpin filter. In some designs the link can be longer, giving a wide hairpin with λ/4 impedance transformer action between ...
It had to rein in its spending to get there; for example, despite its overall operating costs growing by 4.3% year over year, it slashed its largest cost -- sales and marketing -- by 6%.
